WATCH: Jewish extremist attacks Israeli activist with knife

An extreme-right activist armed with a knife assaulted, beat and possibly attempted to stab the head of Rabbis for Human Rights on Friday, a video released by the Israeli human rights organization showed.

Rabbi Arik Ascherman was not hurt in the incident near the West Bank settlement of Itamar, near Nablus, according to a spokesman for the group.

Ascherman was part of a group of left-wing activists that accompanied Palestinian villagers to their fields to harvest olives. Activists often join Palestinians in such excursions to prevent and document harassment and bullying by Jewish far-right extremists.

According to a statement by Rabbis for Human Rights, the harvest ended peacefully but the activists then saw a group of Jewish extremists stealing olives while on a second hill another masked extremist attempted to set several olive trees on fire.

Ascherman said he then confronted the Israeli and attempted to put out the fire. The man warned him to stay away and when he refused to do so, assaulted him, hurling rocks and then pulling out a knife. He attacked and beat Ascherman.

The incident can be seen in the video below, with Ascherman in the blue shirt.

Police said they were investigating the incident. The assailant has not been caught, but officials vowed to show “zero tolerance” towards the criminals involved.
